WATC H QPECIPECATION forming part of Letters Patent No. 583,722, dated February 5, 1895.

Application filed May 24,1894. Serial No. 512,281- (No model.) Patented inSwitzerland November 14, 1893, No. 7,547.

To aZZ whmn it may concern.-

Be it known that I, FRITZ MOERI, watchmanufacturer, of St. Imier, Switzerland, have invented certain new and useful Improvements in Watches, (for which I have obtained Letters Patent in Switzerland, dated November 14-, 1893, No. 7,547,) of which the following is a specification.

The invention consists of an improved watch, its two main bridges secured in approximately the same plane and so that one bridge can be removed withoutdisturbing the other, and between the adjacent edges of which bridges is a serpentine groove exposing to View portions of the gears of the winding up mechanism; also in a stem with a circumferential groove, the stem passing through one of the pillars supporting the bridges and one of the screws securing said bridges having a reduced end to engage said groove.

The invention also consists of an escapement lever and escapement roller of peculiar construction.

My improved watch is shown in the accompanying drawings,in which- Figure 1 is a plan view of the entire watch mechanism. Fig. 2 is a similar view of the same watch mechanism after removing the bridges B and C and also the cock D and balance wheel E. Fig. 3 shows the escapement lever separately. Fig. 4c shows the escapement roller separately, withdrawn from the axis of the balance wheel. Figs. 5 and 6 represent by plan views the under faces of the bridgesB and 0. Fig. 7 is aplan view of the reverse side of the watch mechanism after removing the dial. Fig. 8 is a vertical section illustrating the winding stem passing through and held in place in the post. Fig. 9 is a section showing the connection of the pillars and plates, and Fig. 10 shows the pin of the escapement lever as screwed in place.

In all the figures the same letters of reference refer to the same parts.

Upon the lower plate Aare fixed three pillars a a and a which are provided with threaded holes and suitable shoulders upon which the bridge 13 fits. The cars I) and b of the bridge 13 which fits on the pillars a and a are provided in their upper face with recesses adapted to receive the corresponding ears 0' and c of the bridge 0, which ears are provided in their lower face with corresponding recesses. These ears recessed are of approximately halt the thickness of the bridges, and the corresponding cars l) c and b 0 lap and when brought together the respective upper and lower faces of the bridge B are in the same planes with the respective upper and lower faces of the bridge 0. The screws d and 61 pass through these lapping ears and into screw holes in the pillars a and a and thus secure the bridges B and C in place upon the said pillars a and (L The bridge B is furthermore secured by means of another screw (1 on the pillar 0. The barrel bridge 0 tits on the pillars ct a by its ears above the ears of the bridge B, and it may be removed without disturbing the bridge B. In this bridge B the superior pivots of the other wheels of the watch-work are fixed.

When the bridges B and O are secured in their respective places, their upper and lower faces are in line so that said bridges are on the same level or plane and form together an approximately continuous upper plate. The adjacent edges of the said bridges B and O are shaped in such a way that a serpentine opening is left between the said bridges exposing to view part of the teeth of the gears F and G and also of the pinion H and the click L. This disposition is very useful, as it enables one to control the state of such gearings and to remove the barrel without removing or disconnecting any other gears by this operation.

The stem K passes through the pillar a, said pillar acting as a guide or hearing therefor, and the pinion H and sliding pinion I are connected to and carried by the stem K, the

pinion H gearing with the wheel F. The screw (35' which passes through the ears I) and 0' into the pillar c and thus secures the bridges B and O to said pillar, has its point or extremity reduced, and said point enters and engages a circumferential groove of the stem K located within the pillar a. This prevents The click L is provided with a hole Z which fits over a shoulder provided on the top of the pillar a The latter acts as a pivot for the click L and the screw (1 secures the same in its place be- 5 tween the shoulder of the pillar a and the ears b of the bridge B and at the same time secures the bridges B and C upon the said pillar a The end of the spring-shaped part of the click L carries a pin Z which engages IO in the end of the serpentine opening provided between the bridges B and O, and extends slightly beyond their surface. The object of extending the pin Z beyond the face of the bridges is so that it may be acted upon by hand when the click L is to be released from the teeth of the ratchet G- in order to unbend the motive spring. The pivot of the click being actuated between its mass and its elastic part, the former has only to bear the pressure 0f the motive spring. Thehandsetting lever M and its spring at are also made of one piece, the strong part of the lever being connected to the push-piece.

The minute wheel bridge N is formed and arranged so as to keep the following parts in their places: the minute-wheel, the free end of the lever M, and the pinion H in order to prevent the same from following the sliding pinion I when it is slid, so as to act upon the 50 hand setting.

In the anchor eseapement of my improved watch the eseapcment lever O and projecting tongue 0 are in one piece, and the projecting tongue 0 is formed by stamping down the 5 body of the lever O at one end and this operation simultaneously forms the notch or recess o and tongue 0 which extends out at the bottom of the recess The finger p of the escapement roller P shown in Fig. 4 is received in this recess 0'. The said escapement roller P and the finger p are formed of one piece of metal by means of suitable tools, and a recess is provided at one side of said roller beneath said finger. The pinsrof the escapement lever O acting as pallets, are screwed into the said lever O and may consequently be easily removed and replaced.

I claim as my invention-- 1. In a watch, the combination with the plate A, of the pillars 0. a a having shoulders and screw holes, the bridges B and Orcceived upon and supported by the said pillars in approximately the same plane and the screws (1 d d for securing the bridges in place, the adjacent edges of said bridges being correspondingly curved so as to form a curved or serpentine groove or opening exposing to view the engaging teeth of the wheels, substantially as set forth.

2. In a watch, the combination with the plate A, of the pillars a a a having shoulders and screw holes, the bridge B adapted to fit upon said pillars and having ears I) b recessed in the upper face of the bridge, the bridge 0 also adapted to fit upon said pillars and having ears 0 c recessed in the under face of the bridge, said ears being each of approximately halt the thickness of the bridge, whereby the bridge 0 can be independently removed, and the upper and lower faces of said bridges are in the same planes, substantially as specified.

3. In a watch, the combination with the plate A, of the pillar a, the stem K passing through the pillar a and having a circumferential groove inelosed by the pillar, the bridges B C in part fitting over the pillar a, the screw d having a reduced end and passing throughsaid bridges into the pillar a and the reduced end into the groove of the stem, whereby the same screw retains the stem in place and assists in securing the bridges in place, substantially as specified.

4. In a watch, the combination with the plate A and pillars, of the bridges B and C supported by said pillars in approximately the same plane and having a serpentine groove between the adjacent edges of said bridges, the click L pivoted on one of said pillars having a spring-shaped part and a rising pin Z on the end thereof, said pin being received in the base of said serpentine groove, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
